Abstract (en)

[origin: WO2020127742A1] The invention relates to a method for separating trace substances from contaminated water, wherein water contaminated by trace substances is first coarsely filtered and then filtered by a filter membrane, wherein the filter membrane has a polymer matrix, pores and 3 to 70 wt% adsorbent, preferably 40 to 60 wt% adsorbent, 0 to 5 wt% additives, 0 to 5 wt% pore inducers, residual polymer, wherein the adsorbent and, as applicable, the additives and, as applicable, the pore inducers are embedded in the polymer matrix, wherein the filter membrane has an inflow for the coarsely filtered water and the waste water then permeates the filter membrane, wherein trace substances contained in the coarsely filtered water are adsorbed at least in part on the adsorbent.
